I Application filedlune 2, 18.99.

To all whom it may concern.- 1

Be it known that 1, Greece M, Lrenr, a citizen of the United States, residing at Pomeroy, in the county of Garfield and fitateof Washington, have invented a new and useful Land scraper, of which the following is a specification.

The invention relates to improvements in land-scrapers.

e je t o he rresenti v tinn i o mpro e h on t u n of land-s rape s an to provide a simple and comparatively inexpen sive one adapted for general leveling pur; poses and designed especially for leveling fields after the same have been plowed and capable of breaking the lumps and of packing the earth suiiiciently to obviate the necessity of using a land roller. j

A further object of the invention is to provide a scraper of this character which will possess great strength and durability and which may have its blades readily adjusted and arranged at different inclinations to effect the proper operation or action on the soil.

The invention consists in the construction and novel combination and arrangement of pa h af r l y desc d, ll strated in the accompanying drawings,- and pointed out in the claims heretg appended.

I the draw ng Fig e l s a persp ctive e o a land-sc aper con ru ed i accor ance ith this nve ti Fisv2 s a plan View. Fig. 3 is detail view illustrating the manner of hinging the scraper-blades to the nn iner ers, t Like n mera o referen e spending parts in all the figures of the drawings.

l designates a transverse bar located at the ront o he scraper nd hav ng hesection 2 he of c nn cte with it and orm ng a main ee, t h ch he draf is inp and he said section which y be of any desired number, consist of front and reel c p -b 3 and 4, connected by the means hereina r described and desig e to be arranged at an inclination, as clearly illustrated in Fig. 1 of the accompanying drawings. In the accompanying drawings a scraper consisting of three sections is illustrated, and the clevis or draft attachment is arranged cendelsignat-e none I seen r5. 719,1 17. (No model) .trally of the main whifi letree-bar 1, a threehorse evener being designed to be provided forequalizing the draftof three horses. One

' horse is to be provided foreach of the sections of the scraper,.and when four sections are used a pair of doubletrees may be coupled to the main whifiietreebar at points equidistaut of the ends thereof instead of providing may be of any desired construction.

The-frontand rear scrapenblades 3 and 4' are connected by central and side longitudinal bars 6 and'7, provide'd at their ends with eyes 8 and secured to the inner faces of the scraper-blades, near the upper edges thereof, by pintles 9, passing through the eyes'and having their ends enlarged and seen red to the rear faces of the frontscraper-blades and to thefront faces of the rear scraper} blades.

wardly-converging braces 10, secured at their rear ends to the side connecting-bars,nearthe rear terminals thereof, and connected at their front ends to the central bar 6, near the front end thereof. 7

The front and rear blades 3 and 4 are provided near their centers with upwardlyexten ding bifurcated arms 11 and 12, which are connected with an operating or shifting lever 13 by a bar 14, provided between its ends with a curved ratchet 15 located above the fulcrum-point 15 of the operating or shifting 1erer; "The Operating or shifting lever, which or bracket 147', audit-is pivoted at 1813; the cennecting-barli, The curved ratchehwhich isprgvided at its upper edge with suitable teeth or notches, is engaged bya spring-actuated dog or detent carried by the operatingleverand connected with a suitable 1atch-leyer 19, locatedadjacent to the handle ,0? grip shifting the lever forward and rearward the inclinat on of he c per lad y. be changed, as will be readily apparent. V

The connecting-rods 14; are provided at their front ends with series of perforations 20,adapt' ed to receive the pivots 21, which connect ing the pivots 21 in the different perforations a central clevis or draft attachment which isfnlcrumed on a suitable bolt or pivot 16,- has itslower end arranged within a keeper 1 ef the operatinglever and adapted to be r ssed .sim l an n ywith e eine: y

the bars 14 with the arms 11, and by adj ust= The longitudinal bars are supported. by forbreaking the lumps, and by arranging the rear scraper-blades at a greater inclination they will operate to pack the soil after the same has been leveled by the front scraper-blades.

The front and rear scraper-blades of each section are designed to be of different lengths,

as clearly illustrated in Fig. 2 of the accompanyingdrawings, in order to break the joints and arrange the spaces or openings between the adjacent ends of the front scraper-blades outofalinementwith those oftherearscraperblades, so that any ridge left by the front blades will be leveled by the rear ones. By this arrangement the scraper is enabled to leave the surface of the land operated on perfect-ly smooth and free from ridges.

The front scraper-blades are provided at their upper edges with clevises 22, which engage rings 23 of short chains 24, extending from the upper edges of the front scraperblades to the transverse bar 1 and secured to the latter by any suitable fastening devices, such as staples, clips, or the like.

It will be seen that the land-scraper, which is simple, inexpensive, strong,'and durable, While being designed forgeneral leveling purposes is especially adapted for operating on fields during the process of cultivation and that it is capable of leveling the soil, breaking the lumps, and packing the earth. The scraper-blades may be readily shifted and arranged at the desired inclination, and the angle or inclination of the front scraper-blades may be different from the rear scraper-blades, whereby the front ones will level the soil and break the'lumps and the rear ones will be caused to pack the earth. The number of sections may be Varied, and by employing blades of different lengths for each section the spaces or intervals between the blades will be out of alinement, and any ridges left by the front scraper-blades will be leveled by the rear ones.

Changes in the form, proportion, size, and the minor details of construction Within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

What is claimed is- 1. A scraper provided With-front and rear blades and having means whereby the blades may be set at different inclinations to cause the front blade to level the soil and break the lumps, and the rear blade to pack the earth, substantially as described.

2. A scraper comprising front and rear blades, connections between the blades having the latter hinged to them, and operating mechanism mounted on the said connections and adapted to adjust the blades and hold the same at the desired inclination, substantially as described.

3. A scraper composed of sections having front and rear/blades of different lengths, whereby the spaces or intervals between the adjacent ends of the front blades will be out of alinement with those of the rear blades, substantially as described.

4. A scraper comprising a series of sections having front and rear blades hingedly mounted and adapted to be arranged at an inclination, operating mechanism mounted on the sections and connected with the front and rear blades, a transverse bar arranged at the front of the scraper and forming a main whiffletree, and connections between the upper portions of the front blades, and the trans verse bar, substantially asdescribed.

5. A scraper comprising the front and rear blades 'hingedly mounted, a longitudnal bar adj ustably connecting the blades and adapted to set the same at different inclinations, and operating mechanism connected with the longitudinal bar and adapted to shift the blades simultaneously, substantially as described.

6. A scraper comprising front and rear blades hingedly mounted and provided with upwardly-extending arms, connections between the blades, a longitudinal bar pivoted to the arm of the rear blade and adjustably connectedto thearin of the front blade, an operating-lever fulcrumed on the said connections and connected with the longitudinal bar, and means for locking the operating-lever, substantially as described.

'7. A scraper comprising front and rear blades, the central and side connecting-bars hinged to the blades, braces connecting the said bars, and operating mechanism mounted on the central bar and connected with the blades, substantiallyas described.

8. A scraper comprising a series of sections composed of front and rear blades and connectingbars having the blades hinged to them, operating-levers fulcrumed on the connectingbars, longitudinal bars connecting the levers with the blades and a transverse bar arranged at the front of the scraper and connected with the front blades, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signaturein the presence of two witnesses.
